monitor beehives in remote areas
The European honey bee is not a native species in New Zealand or Australia. Well meaning naive people think hosting bees is a great idea. The reality is it robs the native insect population of a food source.

Native pollinators have different life cycles and different plants they evolved to get food from. Honeybees, likewise, will only visit some flowering plants. That may increase competition for scarce resources, or it may not.
You are correct that honeybees are non-native, and that honeybees do draw a few lbs of nectar and pollen every day from the environment (up to a 3 mile radius from their hive), but it's unclear how much of that nectar and pollen is surplus from the plants or removed such that local bees experience pressure.
It is similarly naive to view the introduction of a species through the lens of pollen quantity being 'surplus' or 'enough'. The presence of rival pollinators affects native insects whether or not there is a shortage of food - for example by discouraging presence, by occupying nesting sites, by altering endemic predation webs, and similar.
